Everything you need to know: September equinox 2012


Happy equinox to all! The 2012 September equinox will arrive later this week, at 9:49 a.m. CDT (14:49 Universal Time) on September 22.

The 2012 September equinox comes on September 22, at 9:49 a.m. CDT (14:49 Universal Time).
Translate to your time zone.

In the Northern Hemisphere, the sun is rising later now, and nightfall comes sooner. The time of the autumn equinox is here, when the days are getting shorter, and day and night are approximately equal in length.

For us in the Northern Hemisphere, people are enjoying the cooler days of autumn even as preparations for winter are underway. South of the equator, spring begins.
